- Be it known that LPERRY A. DE GAnMo, a citizen of the United States, residin at Stratton, in the county ofI-Iitchcock, gtate of-Nebraska, have invented a new and useful Subpacking-Ring for Disks; and I do hereby declare the following to be'a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use the same.

The present invention relates to a subpacking ring attachment'for disks, and has for its object to provide .a device of this character which embodies novel features of construction whereby it-can be readily applied to a disk, thereby enablingthe disk to answer the purpose of two farm implements.

Further objects of the'inve'ntion are to provide an attachment of this character which is comparatively'simple and ineXpen in its construction, which can be readsl've ily applied to the disk or removed therefrom, which will not bend or injure the edge of the disk in any manner, and whicheliminates the necessity of having two independent farm implements.

With these and other objects in view, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description pro ceeds, the novel features thereof being pointed out in the appended vclaim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawing, in which ,1

Figure 1 is a side elevation of a disk provided with a subpacking ring attachment constructed in accordance with the invention, one of the segmental sections of the attachment being indicated by dotted lines as swung outwardly away from the disk.

Fig. 2 is a transverse sectional view through the disk with the attachment thereon.

Fig. 3 is an edge view of the same, portions being broken away and shown in section to illustrate more clearly the hinged connection between the segmental sections of the attachment.

Fig. 4 is a similar view, looking at the device from the opposite edge, and showing the clamping screw for drawing the segmental sections into operative position.

Referring to the drawings, WlllCh lllllS- trate one embodiment of the invention, the

numeral 1 designates a disk which is "of the conventional shape and configuratiombe ing concave on one side and convex on the opposite side. formed in series of complemental and interchangeable segmental sections 2 which are adapted tobe applied to the edge of the disk and clamped in position thereon. In the present instance there are two of the sections 2, each of which issemi circular in shape, although the exact number of the segmental is not material to the invention. These segmental sections 2 are connected at one end by a hinge plate 3, said ends being slit longitudinally at 4: to receive the hinge plate 3 also be observed that the hinged ends of the sections 2 have the outer corners thereof rounded at 6 so that the sectionscan be readily swung apart when applying the attachment to a disk or removing it therefrom. Any suitable clamping means may be provided for detachably connecting the free ends ofthe segmentalsections 2. In the present instance one of the sections can ries a clamping screw 7 which'has the head thereof exposed within a notch 8 in the periphery of the section, the threaded end of the screw being adapted to engage the opposite segmental section, so that by tightening the screw the two sections can be drawn securely together.

The inner faces of the segmental sections 2 are grooved at 9 to receive the edges of the disk 1, inwardly projecting flanges 10 and 11 being provided upon opposite sides of the said groove. The outside flange 10 is considerably wider than the inside flange 11, and has the inner face thereof beveled at 10 so that it will fit squarely against the convex outer face of the disk 1 and obtain a firm bearing thereon. The inside flange 11 is shorter than the outside flange 10, and is. designed to be arranged on the concave side y Patented a naa'iaie, a pnanoa filed September 2s,.191e.' Seria11 lo.122,682.

The' sub-packing Q ring is which is engaged by the pivot pins 5.

sections which may be employed v fiepien of this patent may be outer side of the disk 1, the edges of the disk are relieved of the load, and the attachment can be used Without danger of bending or in urmg the edges of the disk.

The outer periphery of the packing ring attachment may have any desired configuration. InFlg. .l. the outer edge 1s substantially semi-circular in cross section although this outer edge may have a V-shaped cross section, as indicated by Fig. 5, or a square cross section, as indicated by Fig. 6.

'VV hen the attachment is clamped in position upon thedisk, the device can be used as a sub-packing ring, and by the use of this attachment the necessity of providing a separate implement is avoided, since the one implement can beused for both purposes. Where a larger number of segmental sections is used, these sections may be detachably connected, to admit of the device being readily fitted upon large or small disks.

A slightmodification is shown by Fig. 6, in which a filling strip 12 is provided for obtaining a tight engagement with the disk obtained for five cents each, by washimztnn. D. 0.

in the event the latter. should have become slightly ing ring attachment would otherwise be loose thereon. This filling strip 12 may it against the beveled inner faces 10 of the outside flanges 10, and the outer edge thereof may be returned at 12 to fit around the edge of the disk 1. Proper compensation will thus be made for wear, and the device can be tightly clamped upon the worn disk.

aving thus described the invention, what I claim as new and desire to secure by Letters Patent, is 2* The combination with a disk. oi a subpacking ring formed in a series of segmen tal sections formed upon their inner faces with V-shaped 7 of the disk, and a removable V-shaped fill-- ing strip inserted between the edges of the disk and the base of the groove to C()11'l] )(l] sate for wear of the disk.
